With this in your M1 folder, you can drop any map (in that folder) on it, regardless of name, and double-clicking on your Marathon app starts a game using that map. Want to use a different app? Drop it on Map Select, and it will be the one modified with new map names. Brings some of the convenience of M2 to M1...

Lets you move different levels between Map files. You can make a Map file with only Waldo World Arena in it to bring to net games, for example. (Warning: this program is incompatible with maps made with the latest versions of Pfhorte, and the author has no plans to update it.)

This map pack are completly redone versions of the original Marathon net maps. Also the level G4 sunbathing was converted and changed into a net map in this pack. More novelty than anything now... but still interesting for its time.
